Many countries around the world have implemented blockchain technology initiatives to various extents. Some of the notable ones are:
1. Estonia: Estonia is often considered a world leader in blockchain technology. It has implemented blockchain-based solutions for public services, healthcare, and voting systems.
2. Singapore: Singapore has invested heavily in blockchain technology and has used it for various purposes such as trade and finance.
3. Dubai: Dubai has set a goal to become the world's first blockchain-powered government by 2020. It has implemented blockchain-based solutions for property registration, payment systems, and more.
4. China: China has implemented blockchain technology for a variety of purposes, including supply chain management, digital identity verification, and copyright protection.
5. Switzerland: Switzerland has emerged as a hub for blockchain technology due to the supportive regulatory environment. It has implemented blockchain-based solutions for finance, healthcare, and more.
6. United States: The United States has implemented blockchain technology in various sectors, including finance, supply chain management, and voting systems.
These are just a few of the countries that have implemented blockchain technology initiatives. As blockchain technology continues to gain popularity, we can expect more countries to join the list.
First of all, we need to understand why we want to use this or that technology. For fishing, the block chain technology is of little use, because the block chain requires objective primary data, which are not yet available in fishing. With the help of the block chain, trace the supply chain from the port to the consumer. This is probably interesting and important, if all the English-speaking fishing countries do it. However, Estonia, Switzerland and Singapore are not fishing countries due to the absence of fish stocks in the EEZs of these countries. I myself am Latvian by nationality and have been to Latvia and Sweden, and in Kaliningrad there is our Russian fishing university, and I know the state of stocks in the Baltic Sea. So if there are fish stocks in your EEZ, you need to investigate not the block chain, but the fishery statistics, which so far no one has established, except for the United States. And in order to have good fishing statistics, you need to either keep qualified inspectors on each fishing vessel who will work 24/7 for $700 a day, as in the USA, or model fishing processes based on the parameters of fishing gear and the time of their use. We in Russia follow the second path, beginning with the studies of Professor Baranov (1918).
